バックエンドの開発者は、POSTリクエストにこれらの指示を与えていました。
プロトコルで5番と何の経験を持っていない、私は検索し、私のコードで終了しました。
-(id)initWithURLString:(NSString *)URLString withHTTPMEthod:(NSString *)method withHTTPBody:(NSDictionary *)body {
_URLString = URLString;
HTTPMethod = method;
HTTPBody = body;
//set error message
errorMessage = @"Can't connect to server at this moment. Try again later";
errorTitle = @"Connection Error";
return self;
}
-(void)fireConnectionRequest {
NSOperationQueue *mainQueue = [[NSOperationQueue alloc] init];
[mainQueue setMaxConcurrentOperationCount:5];
NSError *error = Nil;
NSURL *url = [NSURL URLWithString:_URLString];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
NSData *sendData = [NSJSONSerialization dataWithJSONObject:HTTPBody options:NSJSONWritingPrettyPrinted error:&error];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[request setHTTPBody: sendData];
[NSURLConnection connectionWithRequest:request delegate:self];
NSString *jsonString = [[NSString alloc]initWithData:sendData encoding:NSUTF8StringEncoding];
//fire URL connectiion request
[NSURLConnection sendAsynchronousRequest:request queue:mainQueue completionHandler:^(NSURLResponse *response, NSData *responseData, NSError *error) {
//get the return message and transform to dictionary
NSString *data = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
returnMessage = [NSJSONSerialization JSONObjectWithData: [data dataUsingEncoding:NSUTF8StringEncoding]
options: NSJSONReadingMutableContainers
error:&error];
//check return message
if (!error) {

else {
[delegate returnErrorMessageForTag:self.tag];
}
}];
}
私は、JSONにフォーマットされた辞書を渡します。彼は私が右のデータを渡すことができたことに同意します。また、APIに接続できましたが、登録用のデータを送信しようとすると常に「FAILED」が返されます。そこの接続に問題はありませんが、私はデータを転送することができませんでした。
ここで同じAPIを使用しているAndroid開発者は問題ありませんが、iOSに慣れていないので私を助けられませんでした。
私は何が欠けていますか?
このコードのようにしてみてください

直接あなたの答えをコメントするには十分ではない評判ため、この答え。
Swift 1.2
let myParams = "username=user1&password=12345"
let postData = myParams.dataUsingEncoding(NSASCIIStringEncoding, allowLossyConversion: true)
let postLength = String(format: "%d", postData!.length)
var myRequest = NSMutableURLRequest(URL: self.url)
myRequest.HTTPMethod = "POST"
myRequest.setValue(postLength, forHTTPHeaderField: "Content-Length")
myRequest.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
myRequest.HTTPBody = postData
var response: AutoreleasingUnsafeMutablePointer<NSURLResponse?> = nil
私の場合、上記のコードは正常に機能します。
Swift 3、let jsonData = try?JSONSerialization.data(withJSONObject:kParameters)がうまく動作しなかったため、AlamoFireソリューションをコピーする必要がありました。 ..
let body2 = ["username": "[email protected]",
"password": "111",
"client_secret":"7E",
"grant_type":"password"]
let data : Data = query(body2).data(using: .utf8, allowLossyConversion: false)!
var request : URLRequest = URLRequest(url: url)
request.httpMethod = "POST"
request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField:"Content-Type");
request.setValue(NSLocalizedString("lang", comment: ""), forHTTPHeaderField:"Accept-Language");
request.httpBody = data
do {...}
}
public func queryComponents(fromKey key: String, value: Any) -> [(String, String)] {
var components: [(String, String)] = []
if let dictionary = value as? [String: Any] {
for (nestedKey, value) in dictionary {
components += queryComponents(fromKey: "\(key)[\(nestedKey)]", value: value)
}
} else if let array = value as? [Any] {
for value in array {
components += queryComponents(fromKey: "\(key)[]", value: value)
}
} else if let value = value as? NSNumber {
if value.isBool {
components.append((escape(key), escape((value.boolValue ? "1" : "0"))))
} else {
components.append((escape(key), escape("\(value)")))
}
} else if let bool = value as? Bool {
components.append((escape(key), escape((bool ? "1" : "0"))))
} else {
components.append((escape(key), escape("\(value)")))
}
return components
}
public func escape(_ string: String) -> String {
let generalDelimitersToEncode = ":#[]@" // does not include "?" or "/" due to RFC 3986 - Section 3.4
let subDelimitersToEncode = "!$&'()*+,;="
var allowedCharacterSet = CharacterSet.urlQueryAllowed
allowedCharacterSet.remove(charactersIn: "\(generalDelimitersToEncode)\(subDelimitersToEncode)")
var escaped = ""
if #available(iOS 8.3, *) {
escaped = string.addingPercentEncoding(withAllowedCharacters: allowedCharacterSet) ?? string
} else {
let batchSize = 50
var index = string.startIndex
while index != string.endIndex {
let startIndex = index
let endIndex = string.index(index, offsetBy: batchSize, limitedBy: string.endIndex) ?? string.endIndex
let range = startIndex..<endIndex
let substring = string.substring(with: range)
escaped += substring.addingPercentEncoding(withAllowedCharacters: allowedCharacterSet) ?? substring
index = endIndex
}
}
return escaped
}
そして1つの拡張機能:
extension NSNumber {
fileprivate var isBool: Bool { return CFBooleanGetTypeID() == CFGetTypeID(self) }}
これは一時的なもので、より良い解決策でなければなりません...
それが役立つことを願っています...
SwiftはURL-%-encodingの機能を提供しますが、最初のコメントで@nolanwが指摘しているように完全には一致していません。元の質問のステップ5で、何らかの構造内にキーと値のペアを取得したら、エンコード(Swift 4.2)の短くて簡単な代替方法を次に示します。
_var urlParser = URLComponents()
urlParser.queryItems = [
URLQueryItem(name: "name", value: "Tim Tebow"),
URLQueryItem(name: "desc", value: "Gators' QB")
]
let httpBodyString = urlParser.percentEncodedQuery
_
Xcodeの遊び場にそれを貼り付け、print(httpBodyString!)
を加えます。出力には以下が表示されます。
_name=Tim%20Tebow&desc=Gators'%20QB
_
注:これは、基本的なフォームの値(すなわち、バイナリデータではなくなく、マルチパート)のパーセントコードセットのためのものである
Swift 4
let params = ["password":873311,"username":"jadon","client_id":"a793fb82-c978-11e9-a32f-2a2ae2dbcce4"]
let jsonString = params.reduce("") { "\($0)\($1.0)=\($1.1)&" }
let jsonData = jsonString.data(using: .utf8, allowLossyConversion: false)!
urlRequest.addValue("application/x-www-form-urlencoded", forHTTPHeaderField:"Content-Type")
urlRequest.httpBody = jsonData
このコードをSwift?に変換することは可能ですか?.
let myParams:NSString = "username=user1&password=12345"
let myParamsNSData:NSData = NSData(base64EncodedString: myParams, options: NSDataBase64DecodingOptions.IgnoreUnknownCharacters)!
let myParamsLength:NSString = NSString(UTF8String: myParamsNSData.length)
let myRequest: NSMutableURLRequest = NSURL(fileURLWithPath: self.url)
myRequest.HTTPMethod = "POST"
myRequest.addValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
myRequest.HTTPBody = myParamsNSData
var data2: NSData!
var error2: NSError!
辞書パラメーターを文字列に解析します。
-(NSData *)encodeParameters:(NSDictionary *)parameters {
NSMutableArray *list = [NSMutableArray new];
for (NSString *key in [parameters allKeys]) {
id obj = [parameters objectForKey:key];
NSString *path = [NSString stringWithFormat:@"%@=%@", key, obj];
[list addObject:path];
}
return [[list componentsJoinedByString:@"&"] dataUsingEncoding:NSUTF8StringEncoding];
}
そしてそれを使用します:
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPMethod:@"POST"];
[request setHTTPBody:[self encodeParameters:parameters]];
Swift 4.2
func percentEscapeString(_ string: String) -> String {
var characterSet = CharacterSet.alphanumerics
characterSet.insert(charactersIn: "-._* ")
return string
.addingPercentEncoding(withAllowedCharacters: characterSet)!
.replacingOccurrences(of: " ", with: " ")
.replacingOccurrences(of: " ", with: " ", options: [], range: nil)
.replacingOccurrences(of: "\"", with: "", options: NSString.CompareOptions.literal, range:nil)
}
// Set encoded values to Dict values you can decode keys if required
dictData.forEach { (key, value) in
if let val = value as? String {
dictData[key] = self.percentEscapeString(val)
} else {
dictData[key] = value
}
}
